Most likely I will miss this momentous event. Assume best to be buried than cremated to reduce carbon emissions, but in 30 years I expect to have my toes up. If that target is achieved that will be a heck of an achievement and will require a massive change in how we live. It's one thing to set a goal, it's quite another to have the willpower to achieve it. In an era of ease and convenience, it will take a lot of personal development to change behaviours to do something that affects change rather than hope for it, or hope someone else does it for you.
